The Story of Jagersfontein🦉
Jagersfontein, in the Free State, became known for its diamond mine, which produced some of the largest diamonds ever discovered. Its history began long before the mine opened, on a farm whose name would eventually become recognised around the world.
The name Jagersfontein comes from the original farm associated with Jacobus Jagers, a Griqua man who sold the property to C.F. Visser in 1854.
In August 1870, farmer J.J. de Klerk discovered a diamond weighing approximately 50 carats in the area. The find attracted prospectors, and digging began soon afterwards. However, the discovery of richer diamond deposits near Kimberley drew many people away, and Jagersfontein received less attention for several years.
The mine’s fortunes changed as its diamond deposits became better known. In 1893, miners discovered the Excelsior, a remarkable diamond weighing 972 carats. It was the largest diamond known at the time and was eventually cut into several smaller stones. Two years later, another exceptional diamond was found. Originally named the Reitz after Francis William Reitz, president of the Orange Free State, it was renamed the Jubilee Diamond in 1896 to mark Queen Victoria’s Diamond Jubilee. The rough stone weighed 650.8 carats.
By 1893, individual mining claims had been consolidated under one company, which had a working arrangement with De Beers. The mine initially operated as an enormous open excavation, with workers removing the earth largely by hand. Underground mining began in 1909, allowing work to continue beneath the surface. Over its operational life, the mine produced approximately 9.6 million carats of diamonds.
Jagersfontein also attracted geological interest. The deposit is a kimberlite pipe, a formation created when volcanic activity brought material from deep within the Earth towards the surface. The excavation eventually covered approximately 19.65 hectares, making it larger in surface area than Kimberley’s Big Hole.
Mining operations ended on 28 May 1971, shortly after the centenary of the first diamond discovery in the area. De Beers retained prospecting rights until 2002. Years later, companies returned to the site to recover diamonds from old mine dumps, and reprocessing operations began in 2010.
On 11 September 2022, a tailings dam at Jagersfontein failed, releasing a large flow of mining waste into surrounding areas. Homes and infrastructure were damaged, agricultural land was affected, and residents were forced to leave their properties. A subsequent government investigation confirmed two deaths, while a third person remained missing and was presumed dead.
Jagersfontein’s history spans more than 150 years, from the discovery of diamonds on a rural property to the operation of a mine known internationally for its exceptional stones. The mine brought wealth and employment to the area, but its history also includes difficult working conditions, deadly labour unrest and the consequences of mining waste. These events are all part of the story of this small Free State town.
